Cemetery as battleground for 'soul of Singapore':

A shortage of land spurred rigid burial policies in 1998: Only one cemetery, Choa Chu Kang, remains open to burials, and there is a 15-year time limit for burial, after which remains are cremated. Singapore's National Environment Agency says at "closed" cemeteries like Bukit Brown "exhumations are carried out only if the land is affected by redevelopment."
